PECIFICATION forming part of Letters Patent No. 309,765, dated December 23, 1884.

Application lcd April 4, 1852. (Model.)

To all 'wh/0m, t may concern:

Be it known that I, JULns CHAUMONT, a citizen of the United States, and a resident of Voodhaven, in the county of Queens and State of New York, have invented certain new and useful Improvements in Culinary Vessels, of which the following is a speciiication.

My invention relates more especially to that class of culinary vessels which are eniployed for heating liquids and for preparing articles of food. It is advantageous to construct vessels of this character of such a t'orm as to expose a heating-surface at the bottom which is as large as possible in proportion to the capacityY of the vessel, whereby the contents are heated much more quickly and eiTr ciently. Vessels of this description have heretofore been made of castiron or pot-metal; but when thus formed of cast metal they are not only inconveniently heavy, but thei r thickness is so great that heat passesthrough theml with difficulty. Cast vessels are also frangible, and therefore liable to accidental injury. Vessels have also been formed from wroughtiron by the processes technically termed stamping and spinning the sides and bottom ot' each vessel being formed separately and the parts afterward scanned or otherwise united together. Such vessels are of less weight, and are in other respects much more desirable and convenient, than the east vessels, but are liable, after having been in use, to give Way at the seam which forms the junction ot' the sides and bottoni, and thus to become leaky and practically useless. Vessels have also been spun from a blank or single piece ofsheetiron or steel without a seam; but these have heretofore invariably been made of a greater diameter at the mouth than at the bottom, thus affording but a comparatively small heating-surface. Vessels of this form are also very liable to overliow when the contents are in a state of ebullition, as well as to be accidentally overturned.

My invention diifers essentially i'roin all these. It is formed by the process of spinning` from a single piece of sheet-iron or steel, and therefore combines the strength, lightness, and durability of such a vessel with the niechanical stability and large proportionate heating-surface, which is only obtainable by means of the particular form of construction which I am enabled to give it, in which the diameter of the bottom of the vessel is considerably greater than that of its mouth.

In the accompanying drawings, Figure 1 is a vertical transverse section ot' a tea-kettle embodying my invention, and Fig. 2 is a View in elevation ot' a utensil designed for boiling milk, rice, &e.

-In the iigures, A represents the body of the vessel, the sides a c and the bottom b being formed from a single blau k or piece of Wroughtiron. The sides are contracted or drawn in toward the top in such ainanner as to leave an opening, c, the diameter of which is considerably less than that of the bottom b, as indicated by the dotted perpendicular lines f f, let fall from the opposite edges of the opening c. A vessel having a body of this general form may be adapted to various purposes, of which the two shown in the figures are merely illustrations.

The vessel shown in Fig. l, by the addition ot" a bail or handle, c, and a spout, d, forms a convenient tea-kettle. A vessel of the same general form, with the addition of a suitable handle, g. as shown in Fig. 2, forms a saucepan or niillcboiler.

It is obvious that culinary and other vessels for heating liquids constructed in this manner possess great strength and durability, while their weight is comparatively small. The heatingvsurt'aee is very great in proportion to the capacity of the vessel, while they are not liable to overl-low when boiling, or to be easily overturned by accident. These wares maybe finished by any ot' the usual proeesses-such, for example, as tinning, ja-

JanninO or` enamclinv, as the a lication of O I .sa a

the high degree ot' heat necessitated by these operations will not in any way injure a seamless vessel.

I claim as my invention# As a new article of manufacture, a seamless wrought-iron or steel vessel contracted at the upper edge by spinning, so as to make said upper edge of less diameter than the base.
